When faced with microangiopathic haemolytic anaemia, thrombocytopenia and organ dysfunction, clinicians should suspect thrombotic microangiopathy (TMA). The endothelial damage that leads to this histological lesion can be triggered by several conditions or diseases, hindering an early diagnosis and aetiological treatment. However, due to systemic involvement in TMA and its low incidence, an accurate early diagnosis is often troublesome. In the last few decades, major improvements have been made in the pathophysiological knowledge of TMAs such as thrombotic thrombocytopenic purpura [TTP, caused by ADAMTS-13 (a disintegrin and metalloproteinase with a thrombospondin Type 1 motif, member 13) deficiency] and atypical haemolytic uraemic syndrome (aHUS, associated with dysregulation of the alternative complement pathway), together with enhancements in patient management due to new diagnostic tools and treatments. However, diagnosis of aHUS requires the exclusion of all the other entities that can cause TMA, delaying the introduction of terminal complement blockers, which have shown high efficacy in haemolysis control and especially in avoiding organ damage if used early. Importantly, there is increasing evidence that other forms of TMA could present overactivation of the complement system, worsening their clinical progression. This review addresses the diagnostic and therapeutic approach when there is clinical suspicion of TMA, emphasizing complement evaluation as a potential tool for the inclusive diagnosis of aHUS, as well as for the improvement of current knowledge of its pathophysiological involvement in other TMAs. The development of both new complement activation biomarkers and inhibitory treatments will probably improve the management of TMA patients in the near future, reducing response times and improving patient outcomes.

Summary: Carfilzomib has been associated with the development of thrombotic microangiopathy (TMA) in relapsed/refractory multiple myeloma patients, a severe disease with no currently available aetiological treatment. We evaluated the potential role of terminal complement pathway in four patients with carfilzomib‐induced TMA. Membrane attack complex (C5b‐9) deposition on endothelial cells in culture exposed to plasma from patients during the acute phase of the disease suggests complement overactivation as a mechanism of potential endothelial damage in three out of four patients. If confirmed in larger cohorts, C5b‐9 evaluation will allow early identification of patients who could benefit from complement blockade and treatment monitoring. [ABSTRACT FROM AUTHOR]

Background Acute interstitial nephritis (AIN) is an emerging cause of acute kidney disease. While this disease usually follows an acute course, it may occasionally recur, representing a major challenge for the clinician. Methods We performed a retrospective, observational cohort study in 13 nephrology departments belonging to the Spanish Group for the Study of Glomerular Diseases. Patients with biopsy-proven AIN between 1996 and 2018 were included. Results The study group consisted of 205 patients with AIN, 22 of which developed recurrent AIN (RAIN) after a median of 111 days from diagnosis. RAIN was due to a surreptitious reintroduction of a previously known implicated drug or toxic in six patients (27%), sarcoidosis in two (9%), Sjögren's syndrome in three (14%), light-chain-mediated AIN in two (9%) and tubulointerstitial nephritis and uveitis syndrome in two (9%), while in the rest of cases (32%), no precise cause could be identified. Microscopic haematuria was more frequent in patients with underlying systemic diseases. The first RAIN episode was treated with a repeated course of corticosteroids in 21 patients (95%). In six cases (27%), azathioprine and mycophenolate mofetil were added as corticosteroid-sparing agents. During a median follow-up of 30 months, 50 patients (27%) with no recurrences and 12 patients (55%) with RAIN reached Stages 4 and 5 chronic kidney disease (CKD). By multivariable logistic regression analysis, RAIN was independently associated with the risk of reaching Stages 4 and 5 CKD, even after adjusting for potential covariables. Conclusions RAIN is infrequent but is associated with poor kidney survival. RAIN should prompt clinicians to search for an underlying aetiology other than drug induced. However, in a large percentage of cases, no precise cause can be identified. [ABSTRACT FROM AUTHOR]

Introduction: Nonantigen‐specific immunoadsorption (IA) has proven to be effective in acute antibody‐mediated rejection (aAMR). However, there is a lack of solid studies evaluating the safety and efficacy of IA with antihuman Ig‐columns in aAMR. For chronic‐active AMR (cAMR), no studies have evaluated the efficacy of nonantingen‐specific IA with antihuman Ig‐columns. The purpose of this study was to evaluate the role of nonantigen‐specific IA with antihuman Ig‐columns in the treatment of both aAMR and cAMR in kidney transplantation. Material and Methods: In retrospective and observational study, kidney graft and recipient survival rates were assessed after treatment of aAMR and cAMR with nonantigen‐specific IA with Ig‐Flex columns (Therasorb) between January 2012 and May 2018. Protocols included nonantigen‐specific IA, rituximab, intravenous immunoglobulin, and rescue plasma exchange, if necessary. Results: The study included 14 patients with AMR (acute in 9, chronic active in 5). For aAMR, mean follow‐up was 13 ± 6 months, and patient and graft survival were, respectively, of 100% and 83%, with a mean increase in estimated glomerular filtration rate (eGFR) of 7.98 ± 12.96, 10.18 ± 16.71, and 11.43 ± 13.85 mL/min/1.72 m2 (P >.05) at 3, 12 months after treatment, and at the end of follow‐up, respectively. For cAMR, mean follow‐up was 14 ± 8 months, and patient and graft survival were, respectively, of 100% and 60%, with an average increase in eGFR of 4.30 ± 7.86, 5.64 ± 10.47, and 14.5 ± 7.86 mL/min/m2 (P >.05) at 3, 12 months after IA treatment, and at the end of the follow‐up, respectively, although 40% did not respond and required chronic hemodialysis. Conclusion: Nonantigen‐specific IA with Ig‐Flex columns was safe and effective for aAMR treatment in kidney transplantation. In cAMR, IA with Ig‐Flex columns was associated with a satisfactory kidney graft survival, suggesting that IA could potentially offer some benefits supporting its indication in cAMR.

- Abstract
Pregnancy-associated atypical hemolytic uremic syndrome (aHUS) refers to the thrombotic microangiopathy resulting from uncontrolled complement activation during pregnancy or the postpartum period. Pregnancy-associated aHUS is a devastating disease for which there is a limited clinical understanding and treatment experience. Here we report a retrospective study to analyze the clinical and prognostic data of 22 cases of pregnancy-associated aHUS from the Spanish aHUS Registry under different treatments. Sixteen patients presented during the first pregnancy and as many as nine patients required hemodialysis at diagnosis. Identification of inherited complement abnormalities explained nine of the 22 cases, with CFH mutations and CFH to CFHR1 gene conversion events being the most prevalent genetic alterations associated with this disorder (66%). In thirteen of the cases, pregnancy complications were sufficient to trigger a thrombotic microangiopathy in the absence of genetic or acquired complement alterations. The postpartum period was the time with highest risk to develop the disease and the group shows an association of cesarean section with pregnancy-associated aHUS. Seventeen patients underwent plasma treatments with a positive renal response in only three cases. In contrast, ten patients received eculizumab with an excellent renal response in all, independent of carrying or not inherited complement abnormalities. Although the cohort is relatively small, the data suggest that pregnancy-associated aHUS is not different from other types of aHUS and suggest the efficacy of eculizumab treatment over plasma therapies. This study may be useful to improve prognosis in this group of aHUS patients.

Please cite this paper as: Quintana et al. (2012) Influence of renal replacement therapy on immune response after one and two doses of the A(H1N1) pdm09 vaccine. Influenza and Other Respiratory Viruses DOI: 10.1111/irv.12024. Background Patients with end‐stage renal disease have a reduced response to vaccination because of the general suppression of the immune system associated with uraemia. Objectives We evaluated the immune response and differential factors in the immunogenecity to an adjuvanted A(H1N1) pdm09 vaccine (Pandemrix®) in four populations of renal patients after one and two doses of vaccine. Patients Methods 151 patients were included in this study: 58 chronic haemodialysis patients, 52 renal allograft recipients, 14 peritoneal dialysis patients and 27 patients with advanced chronic kidney disease in preparation for kidney replacement therapy. Influenza‐specific antibody levels were measured by monitoring A(H1N1) pdm09 titres using a haemagglutination inhibition assay. Results The seroconversion rate at 42 days after two vaccine doses was 80% in the haemodialysis group, 64·9% in the renal allograft recipients group, 100% in the advanced chronic kidney disease group and 71·4% in the peritoneal dialysis group (P = 0·041). Conclusions Immune response to two doses of the influenza A H1N1 vaccine is dissimilar in the four renal conditions, confirming that seroprotection in pre‐dialysis, haemodialysis and peritoneal dialysis is similar to that in the general population vaccinated with one dose. In contrast, renal transplant recipients with good allograft function showed inadequate protection and triple immunosuppressive therapy including calcineurin inhibitors, mycophenolate and steroids negatively influenced seroconversion after vaccination in renal recipients.

- Abstract
This contribution analyses the treatment of the experience of conflict between human freedom, on the one hand, and the acknowledgement of divine freedom and its power in one’s own life, on the other, as well as the nature of its resolution as Fernando Inciarte presents them in two works: Cultura y Verdad and La imaginación trascendental en la vida, en el arte y en la filosofía. The main thesis is that both freedoms are impossible to reconcile in human terms, and that nevertheless a human life orientated under the acknowledgement of such impossibility opens it to their resolution., Esta contribución ofrece un análisis del tratamiento de la experiencia de conflicto entre las pretensiones de realización de la libertad humana, de un lado, y el reconocimiento de la libertad divina y su poder respecto de la propia vida, de otro, así como de la naturaleza de su resolución tal y como los presenta Fernando Inciarte en dos de sus obras: Cultura y Verdad y La imaginación trascendental en la vida, en el arte y en la filosofía. La tesis principal es que la reconciliación entre ambas libertades es imposible en términos humanos y que, sin embargo, cierta forma de vivir orientada por el reconocimiento de esta misma imposibilidad abre al hombre a su resolución

- Abstract
In this article I unfold, first, the Kantian critic of platonic ideas in order to show the traditional interpretative presupposition according to which ideas in Plato are to be understood as an objective correlate of an intuition. Next, I develop in general terms the hermeneutical limits of such interpretation, showing that this does not make justice to the non-objectivist forms of knowledge introduced by Plato as the locus in which ideas are originary understood. Finally, I present the fundamentals of Wieland’s non-objectivistic interpretation of platonic ideas and their knowledge., En el presente artículo expongo, en primer lugar, la crítica por parte de Kant de las ideas platónicas, con el fin de mostrar el presupuesto interpretativo tradicional que concibe las ideas en Platón como correlatos objetivos de un acto de intuición. A continuación, expongo de modo general los límites hermenéuticos de dicha interpretación, en la medida en que no hace justicia a las formas de conocimiento no objetivistas que Platón introduce como el lugar en el que se conocen originariamente las ideas. Finalmente, desarrollo en sus puntos fundamentales la lectura no-objetivista de las ideas y de su conocimiento por parte de Wieland.

- Abstract
Background M-type phospholipase A2 receptor (APLA2R) is considered the major antigen involved in the pathogenesis of adult primary membranous nephropathy (MN), which is the leading cause of non-diabetic nephrotic syndrome. Antibodies to this antigen have been proved to be an excellent biomarker of disease activity in primary MN. In fact, preliminary data suggest that the higher the antibody level the more proteinuria, and that a decrease in antibody level precedes the remission of proteinuria, but more solid evidence is needed. Methods The present work aims to characterize the predictive value of the level of antibodies against PLA2R as a biomarker of disease course and treatment response in a well-defined cohort of 62 patients from University Hospitals Clinic of Barcelona and Josep Trueta in Girona. The primary outcome was the appearance of a spontaneous complete remission (CR), defined as induction of a CR without the use of immunosuppressive agents. Results In common with other reports, this work confirms that spontaneous CR is more frequent in patients with low titre of APLA2R at diagnosis, but strikingly, in this cohort we found that spontaneous CR was achieved in patients with APLA2R levels <40 UI/mL. Furthermore, spontaneous CR were less frequently observed in patients with proteinuria >8 g/day. Conclusions In conclusion, these findings point out the important role of APLA2R as a tool to predict the disease course and establish personalized therapeutic options at the moment of diagnosis of primary MN. Specifically, patients with low titre of APLA2R (<40 UI/mL) and proteinuria <4/day could obtain benefit of a longer period of follow-up with conservative treatment after diagnosis.

- Abstract
Membranous nephropathy (MN) is estimated to cause end-stage renal disease in ∼ 5% of patients, in whom renal transplantation is the therapy of choice. Among patients receiving a transplant for MN, the disease will recur in the graft in 30–50%; among these, graft loss will occur in 50% within 10 years. Several studies have suggested that phospholipase A2 receptor autoantibody (aPLA2R) levels before transplantation might be useful in predicting recurrence, and their titration after transplantation is clinically relevant to assess the risk of recurrence and progression, to guide treatment indications and to monitor treatment response. In this review we describe the evolving role of aPLA2R as a biomarker in primary MN and its current usefulness in predicting recurrence of this autoimmune podocytopathy after renal transplantation.

[EN]Haemolytic uraemic syndrome (HUS) is a clinical entitydefined as the triad of nonimmune haemolytic anaemia,thrombocytopenia, and acute renal failure, in which theunderlying lesions are mediated by systemic thromboticmicroangiopathy (TMA). Atypical HUS (aHUS) is a sub-typeof HUS in which the TMA phenomena are the consequenceof decreased regulation of the alternative complementpathway on cell surfaces due to a genetic cause. aHUS is anextremely rare disease that, despite the administration ofstandard treatment with plasma therapy, often progressesto terminal chronic renal failure with a high associated rateof mortality. In recent years, research has established thekey role that the complement system plays in the inductionof endothelial damage in patients with aHUS, through thecharacterisation of multiple mutations and polymorphismsin the genes that code for certain complement factors.Eculizumab is a monoclonal antibody that inhibits theterminal fraction of the complement protein, blocking theformation of a cell membrane attack complex. Inprospective studies in patients with aHUS, administeringeculizumab produces a rapid and sustained interruption inthe TMA process, with significant improvements in long-term renal function and an important decrease in the needfor dialysis or plasma therapy. In this document, we reviewand bring up to date the important aspects of this disease,with special emphasis on how recent advancements indiagnostic and therapeutic processes can modify thetreatment of patients with aHUS., [ES]El síndrome hemolítico urémico (SHU) es una entidad clínica definida por la tríada anemia hemolítica no inmune, trombocitopenia e insuficiencia renal aguda, en la que las lesiones subyacentes están mediadas por un proceso de microangiopatía trombótica (MAT) sistémica. El SHU atípico (SHUa) es un subtipo de SHU en el que los fenómenos de MAT son consecuencia de la pérdida de regulación de la vía alternativa del complemento sobre las superficies celulares de causa genética. El SHUa es una enfermedad ultra-rara que, pese al tratamiento estándar con terapia plasmática, frecuentemente evoluciona a la insuficiencia renal crónica terminal, con elevada mortalidad. En los últimos años, se ha establecido el papel clave que desempeña el sistema del complemento en la inducción de daño endotelial en los pacientes con SHUa, mediante la caracterización de múltiples mutaciones y polimorfismos en los genes que codifican determinados factores del complemento. Eculizumab es un anticuerpo monoclonal que inhibe la fracción terminal del complemento bloqueando la formación del complejo de ataque de membrana. En estudios prospectivos en pacientes con SHUa su administración ha demostrado la interrupción rápida y sostenida del proceso de MAT, con mejorías significativas de la función renal a largo plazo y con una reducción importante de la necesidad de diálisis o terapia plasmática. En el presente documento se revisan y actualizan los diversos aspectos de interés de esta enfermedad, con especial atención a cómo los recientes avances diagnósticos y terapéuticos pueden modificar el tratamiento de los pacientes con SHUa., The research carried out by Dr Rodriguez de Cordoba is financedby the Ministry of Economy and Competition (SAF2010-26583),the Autonomous Community of Madrid (S2010/BMD-2316), andthe Fundacion Renal Inigo Alvarez de Toledo.The authors would like to thank Alexion Pharmaceuticals fortheir logistic support in carrying out the consensus meetings,as well as editorial support through Ogilvy Healthworld.

Antecedentes y objetivos: La arteriolopatía urémica calcificante (CUA) o calcifilaxis es una enfermedad rara pero potencialmente mortal que afecta casi exclusivamente a pacientes con enfermedad renal crónica. Para su tratamiento se han empleado diferentes alternativas con resultados irregulares, siendo los bifosfonatos una de ellas. Desde 2002 iniciamos en nuestra Unidad el tratamiento con bifosfonatos en todos los pacientes con diagnóstico de CUA. Material y métodos: Se recogieron prospectivamente, entre 2002 y 2010, ocho pacientes (cuatro hombres, cinco en diálisis y tres con trasplante renal funcionante) con CUA tratados con bifosfonatos. El diagnóstico se realizó por sospecha clínica y biopsia de confirmación. Cinco pacientes con antecedentes de producto calcio-fósforo elevado, seis con antecedentes de hormona paratiroidea elevada (> 800 pg/ml), cuatro paratiroidectomizados, cinco con elevada dosis acumulada de esteroides y seis recibiendo dicumarínicos. Ningún paciente presentaba obesidad ni diabetes mellitus. Resultados: En todos los casos se constató disminución de sintomatología (dolor) a los pocos días y regresión de las lesiones entre 2 a 4 semanas tras iniciar los bifosfonatos, sin cambios en los valores séricos de calcio y fósforo. La mejoría fue más rápida en los que recibieron ibandronato intravenoso. Todos se mantuvieron en tratamiento con bifosfonatos durante al menos 6 meses, hasta que las heridas se curaron completamente. No se han observado recurrencias tras un seguimiento de entre 1 y 9 años. La función renal se mantuvo estable en los pacientes trasplantados. El tratamiento fue bien tolerado y no se observaron efectos adversos. Conclusiones: Los bifosfonatos podrían constituir una alternativa nueva y atractiva para el tratamiento de la CUA.

- Abstract
El síndrome hemolítico urémico (SHU) es una entidad clínica caracterizada por la presencia de trombocitopenia, anemia hemolítica microangiopática y daño renal, demostrando el estudio histológico la presencia de microangiopatía trombótica (MAT). Tradicionalmente el SHU ha sido clasificado en 2 formas: el SHU típico, que ocurre más frecuentemente en niños y es debido mayoritariamente a infecciones entéricas por bacterias productoras de toxina Shiga, y el SHU atípico (SHUa), que se asocia en el 50-60% de los pacientes con mutaciones en genes del sistema del complemento y que tiene un peor pronóstico, causando en la mayoría de los pacientes una insuficiencia renal crónica terminal. En el trasplante renal, el SHU se manifiesta como consecuencia de la recurrencia del SHUa o como un proceso de novo postrasplante. Durante los últimos años, numerosos estudios han puesto de manifiesto que la desregulación del sistema del complemento es la causa responsable del daño endotelial que dispara el desarrollo de la MAT en la mayoría de los pacientes con SHUa. Estos avances en el conocimiento de los mecanismos fisiopatológicos responsables del SHUa, junto con la aparición reciente de nuevas opciones terapéuticas, han permitido desarrollar mejores estrategias para conseguir un diagnóstico precoz y un tratamiento etiológico, que están cambiando la historia natural del SHUa.Esta revisión resumirá, en primer lugar, la entidad clínica del SHUa, para a continuación centrarse en la desregulación de la vía alternativa del complemento como responsable de dicha enfermedad. Finalmente, revisaremos el diagnóstico diferencial y las opciones terapéuticas del paciente con diagnóstico clínico de SHUa.

- Abstract
A typical hemolytic uremic syndrome (aHUS) is a rare disease characterized by nonimmune hemolytic anemia, thrombocytopenia and renal impairment. In the last few decades, a series of studies has established that dysregulation of the alternative pathway of complement plays a fundamental role in the pathogenesis of this disease, leading to endothelial damage and systemic thrombotic microangiopathy (TMA). The prognosis of aHUS is poor, with progression to end-stage renal disease (ESRD) or death in half of patients during the first clinical manifestation., The risk of post-transplantation recurrence of aHUS depends on the genetic abnormality involved. Patients with complement factor H (CFH) mutations have an estimated recurrence rate of 74%, leading to graft loss in 93%. Consequently, isolated kidney transplantation has been contraindicated in these patients and combined liver-kidney transplantation and pre-emptive plasma exchange (PE) have been used as alternatives. However, both strategies have major limitations. Eculizumab, a humanized monoclonal antibody against terminal complement component 5 (C5), has recently been approved for the treatment of aHUS. Recent successful experiences of its prophylactic use in renal transplantation have been reported (one living nonrelated donor and eight deceased donor transplantations). We report an adult patient with aHUS-ESRD with a CFH mutation who received prophylactic eculizumab therapy prior to living-related kidney transplantation

- Abstract
Pregnancy-associated atypical hemolytic uremic syndrome (aHUS) refers to the thrombotic microangiopathy resulting from uncontrolled complement activation during pregnancy or the postpartum period. Pregnancy-associated aHUS is a devastating disease for which there is a limited clinical understanding and treatment experience. Here we report a retrospective study to analyze the clinical and prognostic data of 22 cases of pregnancy-associated aHUS from the Spanish aHUS Registry under different treatments. Sixteen patients presented during the first pregnancy and as many as nine patients required hemodialysis at diagnosis. Identification of inherited complement abnormalities explained nine of the 22 cases, with CFHmutations and CFHto CFHR1gene conversion events being the most prevalent genetic alterations associated with this disorder (66%). In thirteen of the cases, pregnancy complications were sufficient to trigger a thrombotic microangiopathy in the absence of genetic or acquired complement alterations. The postpartum period was the time with highest risk to develop the disease and the group shows an association of cesarean section with pregnancy-associated aHUS. Seventeen patients underwent plasma treatments with a positive renal response in only three cases. In contrast, ten patients received eculizumab with an excellent renal response in all, independent of carrying or not inherited complement abnormalities. Although the cohort is relatively small, the data suggest that pregnancy-associated aHUS is not different from other types of aHUS and suggest the efficacy of eculizumab treatment over plasma therapies. This study may be useful to improve prognosis in this group of aHUS patients.

- Abstract
Agriculture and modern biotechnology are increasingly becoming interdependent, and many new techniques have brought new opportunities for enhancing production and marketing. Germplasm storage is an alternative for the conservation of plant genetic diversity, contributing to the improvement and maintenance of propagation programs for species of interest. In this work, banana corms were collected as plant material from relatively young commercial plantations of three different cultivars: ‘Williams’, Valery (AAA genome; Cavendish subgroup), and ‘Barraganete’ (AAB genome; Plantain subgroup). Their shoot tips were introduced into in vitroconditions, and subcultured monthly to obtain the required number of shoots. The shoots were subsequently rooted and stimulated to invigoration in order to extract apical meristems (0.8–1.0 mm), which were prepared for cryopreservion in liquid nitrogen (−196 °C) following pre-conditioning in PVS2 vitrification solution. Thereafter, the explants were rapidly thawed and then recovered and regenerated using two different methods – by Panis (2009)and Korneva et al. (2009)– consisting of two different sets of recovery and subsequent regeneration media. Statistical analysis of the results showed that the banana cultivar ‘Williams’ demonstrated higher survival and regeneration rates after cry-opreservation using the Korneva method, whereas in cultivars ‘Valery’ and ‘Barraganete’, there were no significant differences between the tested methods. The ‘Barraganete’ cultivar had the lowest survival and regeneration rates, regardless of the applied method.

- Abstract
IgA nephropathy (IgAN), a frequent cause of chronic kidney disease worldwide, is characterized by mesangial deposition of galactose-deficient IgA1-containing immune complexes. Complement involvement in IgAN pathogenesis is suggested by the glomerular deposition of complement components and the strong protection from IgAN development conferred by the deletion of the CFHR3and CFHR1genes (ΔCFHR3-CFHR1). Here we searched for correlations between clinical progression and levels of factor H (FH) and FH-related protein 1 (FHR-1) using well-characterized patient cohorts consisting of 112 patients with IgAN, 46 with non-complement-related autosomal dominant polycystic kidney disease (ADPKD), and 76 control individuals. Patients with either IgAN or ADPKD presented normal FH but abnormally elevated FHR-1 levels and FHR-1/FH ratios compared to control individuals. Highest FHR-1 levels and FHR-1/FH ratios are found in patients with IgAN with disease progression and in patients with ADPKD who have reached chronic kidney disease, suggesting that renal function impairment elevates the FHR-1/FH ratio, which may increase FHR-1/FH competition for activated C3 fragments. Interestingly, ΔCFHR3-CFHR1homozygotes are protected from IgAN, but not from ADPKD, and we found five IgAN patients with low FH carrying CFHor CFIpathogenic variants. These data support a decreased FH activity in IgAN due to increased FHR-1/FH competition or pathogenic CFHvariants. They also suggest that alternative pathway complement activation in patients with IgAN, initially triggered by galactose-deficient IgA1-containing immune complexes, may exacerbate in a vicious circle as renal function deterioration increase FHR-1 levels. Thus, a role of FHR-1 in IgAN pathogenesis is to compete with complement regulation by FH.
